The 5G network operates on the Sub-6 GHz band at 3700–3800 MHz, enabling wide geographic reach combined with strong building penetration. 4G LTE coverage uses multiple frequency bands to ensure consistency across Vietnam's diverse topography spanning coastal plains, river deltas, and mountainous northern regions including Lao Cai, Ha Giang, and Dien Bien.
VinaPhone's 5G stability rate reaches 95.9% — the highest among Vietnam's three 5G operators — with a 5G latency of 30 ms and average 5G upload speed of 55.37 Mbps, according to Ookla's Speedtest Connectivity Report H1 2025. Among the 5 million VinaPhone subscribers who own 5G-compatible devices, 3 million actively use 5G service as of early 2025.

Smaller Subscriber Base Than Viettel: VinaPhone holds 17.49% market share compared to Viettel's 57.6%, limiting network investment scale relative to Vietnam's dominant operator, according to Wikipedia telecom data 2023.
5G Coverage Still Expanding Beyond Core Districts: As of early 2025, VinaPhone targets tripling 5G geographic coverage to reach 99% population coverage by 2030; rural sub-district and hamlet-level 5G coverage remains incomplete in 2026, according to VNPT February 2025.
4G Speed Trails 5G Rollout Priorities: VinaPhone's median 4G download speed of 53.24 Mbps (Ookla Q2–Q3 2023) is strong but reflects Q2–Q3 2023 benchmarks; as network investment shifts toward 5G densification, 4G performance data in rural areas requires updated independent measurement.
